• Simple storage Hello Storage A minimal owner-controlled storage contract for first deployments. Use only as a learning contract.
• Token ERC20 Mintable Mintable ERC20 token with an owner-controlled mint function. Decide and publish minting policy before community launch.
• Capped token ERC20 Capped Burnable ERC20 with capped supply, burn support, and controlled minting. The cap is enforced in token units; confirm decimals and cap before deploy.
• NFT ERC721 Collection Owner-mintable NFT collection with per-token URI storage. Use a durable metadata host before public minting.
• Game items ERC1155 Items Multi-token collection for game items, passes, or editions. Plan token ids and metadata URI format before minting.
• Admin control Ownable Pausable A small admin-controlled contract with pause and unpause controls. Publishing admin powers clearly avoids community confusion.
• Token vesting Vesting Wallet OpenZeppelin vesting wallet wrapper for team or community allocations. Confirm beneficiary, start, and duration; mistakes are hard to unwind.
• Rewards Simple Staking Rewards A compact staking rewards starter using ERC20 stake and reward tokens. Reward math, emissions, and funding need audit before real value.
• Airdrop Merkle Airdrop Merkle proof distributor for community allocations. Root generation and claim list publication must be reproducible.
• Marketplace Fixed Price Marketplace Simple ERC721 fixed-price listing and purchase flow. This is a starter; add fees, cancellation edge cases, and audit before production.
